Estuaries play an important role to create suitable habitat for larval and juvenile fishes but there are little study to evaluate human impact on this function. In this study, investigations of habitat suitability for Ryukyu-ayu, endangered fish species in Amami Oshima Is, were conducted in two contrasting estuaries focused on the physiological condition and feed resource distribution by using field observation and numerical 3D flow simulation results. As a result suitable area was strictly limited in the modified estuary and numerical experiment results support that tidal flat restoration can create twice area of suitable habitat compared present condition.
